WRENCH.

To all whom it may concern:

Be it known that I, SETH C. FOSTER, a citizen of the United States,residing at Nashville, in the county of Davidson and State of Tennessee,have invented certain new and useful Improvements in Wrenches; and I dohereby declare the following to be a full, clear, and exact descriptionof the in vention, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention relates to new and useful improvements in wrenches, and myobject is to provide for the ready and effective adj ustment of the sameto a nut or other obj ect to which it may be applied for removalthereof.

The invention also contemplates simplicity and facility of operation andcheapness of manufacture.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claim.

Referring to the accompanying drawings which are made a part of thisapplication, Figure 1 is a view in side elevation of the invention, and,Fig. 2 is a transverse section thereof, as seen on line22, Fig. 1. Fig.3 is a similar view to Fig. 2 showing a modified form of spring.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this application, wherein likecharacters of reference denote corresponding parts in the several views.

In carrying out my invention, I provide a handle member 1 having, asusual, at one end, a fixed jaw member 2 and upon said handle member 1 isarranged a movable aw member 3, said latter jaw member being adapted, asshown in Fig. 2, for the passage therethrough of said handle, suchadaptation being effected by forming said jaw member with an opening orpassage therethrough of angular outline to conform with the crosssection of said handle as at 4. The movable jaw 3 is provided orequipped with a quick-threaded screw 5 adapted to engage a correspondingratchet or toothed surface 6 on the handle 1, as seen in Fig. 1, theaction of which will be apparent. baid quick-threaded screw has passingcentrally through an opening 7 therein, a lever 8 pivoted as at 9 tosaid movable jaw, said screw being adapted to slide upon said lever, aswell as to rotate upon the same, in actuat- Specification of LettersPatent.

ing said jaw. The lever 8 also extends through a passage 10 in anextension 11 of the jaw member 3, said passage or recess beingelongated, as seen in Fig. 2, to permit said lever to be moved laterallyor outwardly in a direction away from the handle for the disengagementof the nut 5 from the toothed or ratchet surface 6, as also, of course,to allow of reengagement between said parts. The extension 11 isequipped with a spring clasp or holding device 12 adapted to be actuatedby the thumb or finger, which has its inner edge formed with a shoulder13 arranged in a lateral slot or opening 13 in said extension, foreffectively holding the lever 8 when the screw 5 is in position forengagement with the toothed surface 6 or for holding said lever whensaid screw is out of engagement with said toothed surface, as indicatedin Fig. 2.

A longitudinal slot 14 is provided in the handle 1 for the reception ofthe inwardly projecting end of a pin or stud 15 extending through the awmember 3 for limiting the outward movement of said jaw member and toprevent displacement of the same.

It will be noted that in using the wrench, the aw members are suitablyapplied to the nut or other object, previous to which, how ever, thelever is moved outwardly so as to disengage the screw 5 from the ratchetsurface 6 of the handle, as required to allow of the movement of themovable jaw manually to its initial position with relation to the nut orother object. After such movement of said jaw, the lever 8 is moved toits original position and is thus held by the action of the spring clasp12, again efiecting engagement between the screw 5 and the ratchet ortoothed surface 6.

In order to jam or bring the jaw 3 into more effective contact with theobject or nut, the quick-threaded screw 5 is suitably actuated foreffecting that purpose, as will be readily appreciated.

From the foregoing, it will be seen that a simple, cheap and effectivewrench is provided for readily carrying out its intended purpose, as inturning nuts upon bolts or applying the device for other purposes forwhich it may be applicable.

I claim:

A wrench comprising a handle having a toothed or ratchet surface and afixed jaw, 21 slidable member having a jaw at one end 1 opposed to theaforesaid'jaw and a lateral extension at its opposite end provided witha slot in one side and a slot extending therethrough at right angles tothe plane of the aforesaid slot, said slidable member being arrangedupon said handle, one of said slots being adapted to receive a springclasp, a quick-threaded screw adapted for engagement With said ratchetsurface, a lever pivoted to the jaw of said slidable member and carryingsaid quick-threaded screw said (mick-threaded screw having rotatable andsiidable connection with said lever, the other slot of said lateralextension being adapted to receive the free end of said lever and topermit lateral movement of said lever for the adjustment of saidquick-threaded screw with relation to said ratchet surface ofsaidhandle, said spring clasp being adapted to engage said lever for itsautomatic retention in fldJlIStBCl position, said handle also having alongitudinal slot receiving a projection or stud from said slidablemember for limiting the movement of the latter.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
